Any body any experience of removing "old" oil staining from granite paviors?

Granite is so dense, i would assume the oil hasn't travelled very far into the block. Maybe try your normal oil remover with some decent dwell times?
-
All the obvious things/formulas have been tried .
-
They would probably be 10mm of granite with the rest concrete cast, granite faced blocks... just letting you know... whether or not it makes a difference to the way you get rid of the stain I do not know
-
What have you tried ?
-
I'm no expert on oil removal and I say it like many others, I haven't mastered it but I've tried alsorts on the very same surface and had no joy.
In my opinion that can't be removed. But I'm no expert in oil/fuel stain removal.

Have you tried something mixed with wall paper paste?

I have never got oil out of any surface. Working with Lee on Saturday there was some oil all over the sandstone. I said that the slabs would want lifting and replacing. I know if I had paid for the slabs to go down I wouldn't settle for oil all over them.
Chris
Look at proper poultices -wall paper paste free ones ;D, proper dwell times etc but promise nothing
Good luck

Too big a job for a poltice there is approx 10,000sgm to clean and seal. I am flying back out too Ireland tomorrow night to try some more products and just need a few more ideas....i just dont too be able to come up with a solution!

Steam
Or put oil on the lot and even it up!
Rob ;D

Poultices are a good idea as the whole 10 000 sqm is not covered in oil!

What about those bio oil cleaners that you can get? they contain active enymes that feed on oil, right into the paving and die off once all the oil has been devoured... same thing as they use in oil spills in the sea, I believe oil technics do one and there is another company that do one, can't remmeber the name.
You could put it down, leave it for few days then return?

WonderMicrobes is a multi-culture concentrate available in liquid form. It is composed of at least twelve select microbial cultures and enzymes designed to bioremediate almost all fractions of crude or modified petroleum products and paraffin wax. They are also effective on animal and vegetable oils and fats.
Powerful soaps in WonderMicrobes break the hydrocarbons into minute molecules. The microbes then attach themselves to the contaminants and reduce them to carbon dioxide and water. The microbial cultures continue enzyme production until all oil contaminants and other organic wastes are consumed. WonderMicrobes is non-toxic, non-caustic, non-corrosive, non-pathogenic (harmless) and is biodegradable.
Application
WonderMicrobes effectively removes surface and embedded stains from spilled petroleum products on concrete and asphalt garage floors, driveways, shop floors, loading docks, fueling areas, parking lots and oil storage areas. It inoculates the contaminants with bacterial cells and oxygen catalysts necessary for complete biodegradation. This formula can also be used for washing soil, sand, gravel and loose rocks and for cleaning heavy machinery.
Equally successful for light petroleum, lubricating oil, gasoline, kerosene and diesel spills
Effective for cleaning cooking oils and fats including grease trap maintenance.
Shortens clean-up times for oil spills and stains
Cleans oily equipment, vehicles, tools, floors, stoves, cabinets and carpets.
Cleans up spills from hydraulic brake lines and equipment failures
Contains no petroleum distillates or solvents
Contains essential microbial nutrients and oxygen catalysts
Enhances biodegradation above and below ground surface, when used as recommended.
Economical and ecologically sound
Eliminate removal and replacement of contaminated materials
Properties
pH 7.0 - 8.0
Instructions
Shake or mix thoroughly before dispensing.
Hard Surface Cleaning: Dampen the contaminated surface, apply WonderMicrobes and allow it to work for 20 -30 minutes, then brush and rinse. Keep the work site damp during treatment and repeat if necessary.
Porous Surface Cleaning: Scrape surface, dampen and apply product. Leave on the surface a minimum 2-3 hours. Use burlap cloth or similar breathable moisture holding covering if longer periods of time are necessary. Scrub the surface periodically if dirt is heavily compacted. Rinse.
For soil remediation: Apply 1.0 gallons per cubic yard of soil to be treated. Soak the soil thoroughly after application. Keep soil damp during remediation which may take several weeks. Air tubes inserted into the ground for deeper contamination will accelerate rate of bioremdiation.
Tank Cleaning: Dilute 1:3 and apply by sprayer. Leave on the surface for 10 - 15 minutes, to allow penetration, and remove with a pressure washer (use dechlorinated water). 1 gallon of concentrate should treat 100+ feet of tank surface.
Tanks that have larger quantities of remaining hydrocarbons should be filled with water and aerated during remediation period.
Precautions/Limitations: Read and follow precautions on MSDS. Pretest new equipment finishes by applying to a small area first. Optimal performance is on damp concrete surfaces.
Dilutions:
Full-strength - heavy aged oil stains (wet the surface with water before applying. Follow first application with diluted product for better activity)
1:3 - tool cleanup and parts cleanup
1:5 fresh oil stains
Storage
WonderMicrobes should be stored between 10º-40ºC (50º-104ºF). Avoid prolonged exposure to higher temperatures. Keep from freezing.
Just got to find a supplier now ;D

A poultice consisting of what?

Kenny has hit the nail on the head Enzymes are the answer ;)
Rob ;D

Has anyone ever tried these type of cleaners? would be interested to know, got a oil stain on a job that has been there over a month, it's on bright white concrete cast flags (I know, probably the worst surface it could be one, sticks out like a sore thumb) and I was thinking about using this type of cleaner, read lot's about them but never tried them.

I have worked with enzymes before ..not that impressed .They are alright in waste traps etc. This was who i worked with before http://www.travena.co.uk/ (http://www.travena.co.uk/)....don't beleive anything they tell you.
-
Im going to do an oil clean up today. Oil filter housing has leaked on a cement slabbed drive. i use a product called OT8 which works on the enzyme principal.
http://www.oiltechnics.co.uk/Oil_Stains/BlockDrives/OT8.html
it has worked for me well in the past using it on monoblock so ill see how it goes today.

Get some before, during & after pictures mate ;)

Aqua Mix Poultice mixed with Aqua Mix Sealing & Coating Remover or even Aqua Mix Heavy Duty Tile & Grout Cleaner may pull it out. Another alternative is to clean it as normal and then seal the lot with Aqua Mix Enrich N Seal which should disguise it enough and seal it against future spills.

Fluoropolymer has been specified ...hence the problem no hiding anything . It is a whole town centre and now it has been cleaned every mark stands out!
There is 100,000 sqm not 10,000 as my original post .

Chris
Show them a test area with my method and I bet they go for it! Lets be honest if it's a Town centre and they leave it much longer it will want doing again in a minute ::)roll

OT8 is great on all type of blocks, though I've never tried on granite, I've never actually come across granite used in this way.
LTP also do some good stuff for oil stains (LTP Spot Stain Remover & Fullers Earth) though works out very expensive and for the area you're talking about it would cost a Richard Branson sized fortune.
-
Chris,
What type of oil is it?

Baby !!

Engine/hydraulic (sp?)

Chris,
I would do a 3 step clean on this,
Resiblock OR first see how much has come out, then OT8 as a follow up clean, this can go on wet/damp surfaces so pretty much straight away after the OR. I'd follow that up with an Hydrofluoric acid wash, safe on Granite, but good quality PPE is very much needed as this is a nasty one to use.
I have used this on Granite before and it will flatten out the surface so might well rid any remaining oil staining. Tensid do the acid, and will send you a sample.
Poultices would be an expensive option and time consuming to do.

Chris if you need some hydroflouric, I'm in Liverpool tomorrow looking a 2 jobs if you need some. 60% tackle, Breaking Bad get rid of dead bodies tackles in plastic boxes, no bath tubs though our kid.
